Another way of extracting low grade copper from its ores economically: (bioleaching) — In bioleaching, bacteria are mixed with the low - grade ore. — The bacteria, carry out chemical reactions and they produce a solution, called leachate. — A leachate, contains the desired metal compound. Extraction after either phytomining or bioleaching:

Bioleaching and phytomining | GCSE chemistry resource
Bioleaching - advantages. Simpler process than smelting and requires fewer expert staff to operate, reducing costs. Produces lower sulfur dioxide emissions than smelting. Phytomining - advantages. Decontaminates polluted ground. Carbon dioxide emissions are lower than for smelting.

GCSE CHEMISTRY
Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.
